About Paul

I am a developer with 5 years of professional experience and a master's degree in computer engineering from Bordeaux.

I currently have solid backend knowledge in both Java and Python: microservices, APIs, databases, etc. I am comfortable with traditional code management tools (GitHub/GitLab), unit testing tools (JUnit/Pytest), linting (SonarLint/PyLint), coverage (Coveragepy), CI/CD (Jenkins/GitHub Actions/SonarQube), frameworks (Hibernate/Flask/FastAPI), databases (Redis/SQLite), and Linux & Windows OS.

I speak fluent English and am a native French speaker, if it is necessary to communicate with people who do not speak Spanish. I also have good writing skills to document and convey the knowledge of the designed product.

Feel free to check out my personal projects on my GitHub! I am currently working on a project about Barcelona's rainfall over the past 2 years: it includes a Flask/Redis Webapp and an API written with FastAPI.
